They are far from the fastest available, but they are pretty much perfect for your purposes. There are some very fancy RAM sticks around, but they can cost up to 10 times as much. What you have is your everyday, garden variety modern PC RAM, which is exactly what you need. DDR2-800, which is what you have, is the sweet spot in PC RAM. You can get much better, but there is no point in your system.. huge extra costs for very little actual performance advantage. In some cases, the high end RAM in the wrong system can actually be a disadvantage, or not work at all. maybe could have got DDR2-1066 instead, if you really wanted that little extra, but the performance advantages would have been minimal anyway.Corsair RAM has a good name, but like anything, they have topline and entry level products. TwinX RAM like this is more on the lower end of the scale, but again, any better is totally un-necessary for home computing, and the benefits of spending a whole bunch more cash would have been very small indeed.If I were building you a new computer, I'd have recommended exactly what you have installed.
